This invention relates to railway eross ings, the primary object of theinvention being to provide continuous rails at railway crossings,eliminating the usual gaps-or spaces between the ends of adjacent railsof crossings. I

An important objectof the invention is to provide a device of thischaracter which may be controlled by an operator from a point re-' motefrom the crossing, the device comprising vertically-movable railsections movable between the ends ofthe rails. r A still further-objectof the invention is to provide 'aidevice of this characterwhich will beprotected against snow and ice, to the end that the device will operateat all times. I

With the foregoing and'other objectsin view, which willappear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in the preciseembodiment of the invention herein disclosed, may be made within thescope of what is claimed, Without departing from the spirit of theinvention.

Referring to the drawings: Figure 1 is a plan view ofa railway cross ingequipped with movable rail sections or V blocks, constructed inaccordance with the invention.

Figure 2 is a sectional view taken on'line 22 of-Figurel. I Figure 3 isa transverse sectional view through the supporting members or chairssupporting the rails of the crossing.

' Figure i is a transverse sectional view through the crossing,illustrating the movable rail sections at the opposite side of thecrossing.

Figure 5 is a vertical. sectional view through one of the movable railsections'or blocks and its operating wedge.

Figure 6 is a sectional 66 of Figure 1-.

Figure 7 is a sectional view taken on line 77 of Figure 1.

45 view taken on line view taken on line guard rails for the railsections 7; Guard the ribs operating in. grooves formed in theRefcrringto the drawings in detail, the reference character 5 designatesthe inner rails of a railway crossing, and the reference character (3designatesthe guard rails thereof. The reference character 7 designatesrail sections of the crossing-that extend at right angles tothe rails 5,the rails 5 and 7 being connected at then ends;

The referencecharacter 8 designates the 0d rails 9 form apart of thecrossing and are spaced fromthe rails 10 that form continuations of thetrack. The rails 11 form con tinuations of thetrack sections 7 andextend in opposite directions from the'rail sections 5, the railsections 11 being spaced from the guard rails 12' that extend inparallel relation with the rail sections 11'. v

The trackrails' and guard rail sections are cast integral with thechairs 13, which chairs are embedded in the track bed to insure againstmovement thereof. Bores-lt extend transversely through the chairs 13,andintersectlongitudinal bores 15, at points inter- V mediate the ends ofthe bores'15.

Operatingiwedges 16 are mounted for sliding movement in the openings 14and 15, the wedges 16 being provided with lateralribs 17 disposed alongthe upper edges thereof, I

Tail section's or blocks-18, so that sliding movement of the wedges 16will produce a vertical movement of the rail sections or blocks. 18 tomove them tort-heir active or inactive positions.

Thus it will be seen that due to this construction, rail sections orblocks are provided at each corner of the railway crossing, and that bymoving the wedges 16', the rail sections or blocks may be moved so thatthe upper ends thereof are flush with the surfaces of the ad- :jacentends ofrail sections forming a'railway crossing, providing a continuoustrack. Supported between the rail chairs are beams 19 that are spacedapart, the beams being connected by means of a transverse bar 20disposed intermediate the ends of thebeams 19. These beams-19, provide asupport for the operating mechanisnr which'includes two independent setsof levers, one set of levers be- NO ing designed to operate the'railsections or blocks at one side of the crossing, while the other set oflevers operates the rail sections or blocks at the other side of thecrossing.

In describing the set of levers as shown by Figure {l of the drawings,it will be seen that the wedges 16 are provided with extensions to jwhich the rods 21 are connected, the rods 21 having their innerextremities pivotally connected to the arms 22 of the bell crank levers23 at opposite sides of the crossing, the inner arms'2 lotfi the bellcrank levers being pivot ally connected to the'links 25 and 26respectively. As clearly shown, one of the links 26 connects with thepivoted arm 27, the opposite link 26 being connected to one end of thepivoted arm 27 which is mounted directly under the arm i The link 25connected with one of the arms 24 connects with one end of the arm 27 at29,

while the opposite link 25 connects with the opposite end of thearm 28,at 30. p The reference character 31 designates operating rods that havepivotal connection with the bell] crank levers, at their inner ends, theopposite ends ofthe rods being connected with the operating rod 32 whichextends along the track and is provided wlth means whereby the rods 31and 32 maybe operated to move the bell crank levers, links and armsconnected therewith, for'operating the wedges 17 and rail sections 18connectedtherewith.

The rail sections or blocks at the opposite sides of the crossing areoperated by the bell crank levers 33 and 34 respectively, the levers 33being connected with the rods 33 that connect with certain rail sectionswhile the levers 34 connect with slmilar rods 34 ,d1SpOSeC l directlythereunder.

The bell crank'lever at one side of the crossing is connected to the bar35, by means of the link 36, the opposite bell crank lever 33 beingconnected to the pivoted-bar 37 Y mounted directly under the bar 35, bymeans of the link 38. One of the bell crank levers 34: connects with oneend of the pivoted bar 37, bymeans'of the link 39, while the bell cranklever 34 at the opposite side of the crossing connects with the pivotedbar 35, through the medium of the link 40. Rod 41 connects with a thebell crank lever 33, while the rod 42 connects with one of the bellcrank levers An operating rod 41 has connection with the rods 41 and 42so that as the operating rod and rods 41 and 42 are moved, the bellcrank levers and wedges will be moved to operate the rail sections orblocks movable between the adjacent ends of the rails forming thecrossing of the track.

In the use of the device, assuming that'a 7 train is moving in thedirection of the arrow as shown by Figure 1 of the drawings, the

' operator will move the rods 31 in thedirection indicated by the arrowA, as shown by Figure 1 0f the drawings, whereupon the rods 21 will 31are moved in the opposite direction to lower the rail sections, and theoperating rods at the opposite side of the crossing will'be moved tomove the bell crank levers and links associated therewith, to elevatethe rail sections or blocks at the opposite side oi? the crossing,providing a smooth crossing and eliminating the usual pounding caused bya train moving over the spaces between adjacent ends of the rails of atrack.

7 I claim:

Ina railway crossing, rail chairs having bores extending horizontallytherethrough, said railway chairs having vertical openings, verticallymovable rail sections operating in the vertical openings, said railsections having grooves in the lower ends thereof, wedge shaped membersmounted inv the horizontal bores, the upper edges of the wedgeshapcdmembers being inclined and positioned in the grooves of the railsect-ions, and levers for 7 operating the wedge shaped members.

In testimony that I claim the foregoing as my own, I have hereto aflixedmy signature. MICHAEL Gr. STOLLER.
